ROLLER-SKATE.

Application filed June 9, 1913.

To all whom it may concern:

Be it known that I, JAMES E. ALLAN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented cer tain new and useful Improvements in Roller- Skates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to roller skates, and more particularly to the mounting or hearing of the rear axle, and the object of my invention is to provide a simple, durable and inexpensive bearing that permits of the free rocking ofthe rear axle of a skate to facilitate guiding the same.

A further object of this invention is to furnish a skate with a tiltable rear axle and novel means for holding the same normally in a horizontal plane.

The above and other objects are attained by a mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein- Figure 1 is a view of the under side of a portion of a skate. showing the disposition of the rear axle; Fig. 2 is a cross sectional view of a portion of the skate, and Fig. 3 is a longitudinal sectional view of the same.

In the drawing, 1 denotes a portion of a foot plate having a conventional form of heel clamping device 2, and depending from the under side of the foot plate is a sheet metal bracket 3 having angularly disposed or rearwardly directed parallel arms 4. The lower ends of the arms 4 are connected by a channel o'urnal plate 5 which has apertured side walls 6 rivetedor otherwise connected to the inner sides of the arms 4. as at 7. The journal plate 5 has end walls 8 cooperating with the arms 4 in providing a housing for a spring block 9 of rubber or like suitable material. The spring block 9 Specification of Letters Patent.

is of less depth than the end walls 8 and said walls are connected by a longitudinally disposed pin 10. The pin 10 extends through a groove 11 provided therefor in the bottom side of a rear axle or rod 12. The rear axle or rod 12 is lnovably held in engagement with the spring block 9 and the ends of said axle extend through slots 13 provided therefor in the side arms 4 of the bracket 3. The ends of the rear axle or rod have revoluble wheels 14 and these'wheels are normally disposed in a plane at right angles to the plane of the foot plate 1, but it is throu h the medium of the spring block 9 that the rear axle rod 12 can be tilted, as shown in Fig. 1. thu. allowing a skate to be easilv guided by the wearer thereof.

What I claim is:

1. In a roller skate, a foot plate, a bearing bracket depending from the heel portion of the plate and provided with slots, a spring block supported by said bearing bracket, a rear axle swiveled against said springbloek and having the ends thereof extending through the slots of said bearing bracket, and a pair of wheels revolubly mounted upon said rear axle. I

2. In a roller skate, a foot plate, a bracket depending from the heel portion thereof, a journal plate carried by said bracket and provided with end walls, a longitudinally disposed pin connecting the end walls of said journal plate, a spring block arranged upon said journal plate, a rear axle fulcrumed upon said pin against said spring block and extending from the sides of said bracket, and wheels revolubly mounted upon said rear axle.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES E. ALLAN.
